What's an Arsenal in a Quiet Residential Neighborhood?

A Surprise in Carmichael:

Video from LiveCopter 3 on Thursday showed deputies seizing a sizable amount of firearms from the Carmichael home. The sheriff's office in its latest release said it had seized about 30,000 AK-47 rounds; 5,000 AR-15 rounds; and tens of thousands of semiautomatic handgun rounds.

On top of the ammunition, the sheriff's office said 21 semiautomatic handguns, four revolvers, 18 rifles, three shotguns, three Polish-made grenade launchers, many armor-piercing rounds, silencers, equipment to make silencers and an array of ballistic safety equipment were also recovered from the home.

The sheriff's office said some of the weapons found in the home were modified to be considered assault rifles under California's penal code. The weaponry has since been moved as evidence into the sheriff's property warehouse.

Deputies first responded to Bodai's home in the 1400 block of Mission Avenue around 1:50 a.m. Thursday after he called dispatchers, himself, the sheriff's office said. Bodai had called saying that there were people in his house who were there to repair a gas leak but were instead eating his food and that he had them at gunpoint.

Dispatchers later in that call heard a gunshot fire off, and Bodai said he shot someone, the sheriff's office said. Deputies who arrived at the home -- with help from dispatch -- calmed Bodai and convinced him to walk outside. He was arrested without the situation escalating

...Bodai showed signs of a mental health crisis, and a gun violence restraining order was issued around 6 a.m., the sheriff's office said.

As the weapons were being seized, three sticks of dynamite with a charge timer were found, prompting a half-mile radius evacuation affecting 1,800 residences, the sheriff's office said. 

...The sheriff’s office first tweeted after 11:35 a.m. for people to avoid the area near Mission Avenue between Fair Oaks Boulevard and Arden Way over a suspicious device. Authorities later said that what they first described as a bomb turned out to be fake dynamite that looked realistic.
